Connecting to a Serial Device

Use a serial cable to plug your serial device into the embedded computer’s serial port. Serial ports P1 to P4 have male DB9 connectors and can be configured for RS-232, RS-422, or RS-485 communication by software. The pin assignments are shown in the following table:

DB9 Male Port		RS-232/422/485 Pinouts
1 2 3 4 5
	Pin	RS-232	RS-422	RS-485	RS-485
				(4-wire)	(2-wire)
	1	DCD	TxDA(-)	TxDA(-)	---
	2	RxD	TxDB(+)	TxDB(+)	---
	3	TxD	RxDB(+)	RxDB(+)	DataB(+)
	4	DTR	RxDA(-)	RxDA(-)	DataA(-)

Installing a SIM Card and SD Card

Installing a SIM Card

The ThinkCore W315/325/345 embedded computers have a built-in GSM/GPRS cellular module to provide long-range communication. SIM (Subscriber Identity Module) cards are used to authenticate and identify subscribers when connecting to a network.

The SIM card and SD card slot are located on the right side of the W315/325’s casing, and on the front panel of the W345.
